We mentioned it here two weeks ago but today it’s apparently finally rolling out to Pixel 8 phones.

It’s also available on the Samsung Galaxy S24, but I guess folks with a Pixel 7 and below will have to wait.
I believe Google visual search (launched in 2017) was added to Bard, so that’s not really new, but the gesture looks handy.
